Title: Muting circuit
Inventor: MURAKAMI OONORI
IPC: H04B1/10
Filed: 1978-12-12
Abstract: PURPOSE:To reduce distortion of an output signal by connecting the emitter of a muting transistor Tr, connected between the output terminal of a signal output circuit and the ground point, to the output terminal and its collector to the ground point. CONSTITUTION:Between output terminal 7 of signal amplifying Tr1 and ground point E, muting Tr4 is provided and its emitter is connected to terminal 7 while its collector is also connected to ground point E. Since when the connection of the circuit like this is IC-implemented, no parasitic diode resides at the emitter of Tr4, no signal clipping is done, causing no distortion. When the emitter area of Tr4 is made to approximate to its collector area as much as possible in case of the IC- implementation of this muting circuit, the current amplification factor can greatly be improved even at a collector-grounded point and potentials at terminal 7 and ground point approximate nearly to an equal value, so that a shock tone based upon a difference in potential between muting operation and non-muting operation can be suppressed.

Title: Scaler chip
Inventor: JIYON II NAASHIYU
IPC: A61C17/00
Filed: 1980-11-04
Abstract: A powered dental scaler is disclosed of a type which drives a vibrating scaling tip in a circular or ellipsoidal pattern of motion. A scaling tip having working surfaces provided by the edges of an elongated, curved element which has a cross-sectional configuration in the shape of a multi-sided figure, e.g., a triangle or a diamond, is particularly useful with a scaler having this type of vibrational pattern. Each of the longitudinal edges has a radius of curvature in the range of about 0.001 inch to about 0.005 inch. The free end of the scaler work tool preferably terminates in rounded or ball-shaped configurations, and the working surfaces can be joined along inactive edges by a convex surface to provide "safe" surfaces. The absence of sharp edges or points on the scaler tool work surfaces substantially reduces the likelihood of damage to tooth dentin, cementum or gums.

Title: Multi-gradation recording system
Inventor: ONO TADAYOSHI
IPC: H04N1/40
Filed: 1985-07-15
Abstract: PURPOSE:To apply multi-gradation recording by forming one picture point into a matrix with plural picture elements at a low-density region, obtaining low gradation density by area modulation and obtaining the gradation density with density modulation of one picture point at middle/high density regions so as to use thermal heads with low resolution. CONSTITUTION:One picture point is expressed by a matrix of 2X2 picture element up to gradation level 3 and one picture point is expressed by one picture element for gradation level 4 or over. Since one picture element of density level 4 is arranged in the 2X2 picture elements matrix when the gradation level is 1. The picture point of gradation levels 2, 3 is obtained similarly by arranging 2, 3 picture elements of density level 4 when the gradation level is 2, 3. Since the picture element of the density level 4 is excellent in density reproducibility, a stable picture point is obtained even at a low density region. At the gradation level 4 or over, a thermal head 1 is powered according to the relation between the predetermined gradation level and the power application time or applied voltage to obtain the picture point density corresponding to the gradation level of a recording signal. Thus, stable and smooth gradation reproduction is attained from the low density to the high density.

Title: Supporting structure for gas turbine combustion device
Inventor: SEGAWA YORIHIDE
IPC: F23R3/60
Filed: 1988-06-22
Abstract: PURPOSE:To suppress the shaking-rotating vibration of a combustor, and not to restrain the thermal elongation and deformation of components of the combustor by supporting an outlet of a internal drum on an inlet of a tail drum and the inlet of the tail drum on a supporting drum by plate springs of a particular shape that are fitted free to slide in the axial and peripheral directions of the combustor. CONSTITUTION:A combustor consists of an internal drum 1, a tail drum 2, an external drum 3, external frame 4, and a combustion nozzle 5 with a turning device. On each end of wing parts that are extended diagonally on the same side from the middle part and from the both sides of the middle part and are curved, a pressed round parts 11 is formed, and the round part has a sectional shape of convex arc on the opposite sides of the middle part in view of the section perpendicularly intersecting with the center line of the wing part. The plate springs are inserted between the periphery surface of the tail drum inlet 6 and internal surface of the supporting drum 3', and between the periphery surface of internal drum inlet 7 and the internal surface of tail drum inlet, distributing them around peripheries. The plate springs are fitted so as to slide in the axial and peripheral directions against the supporting drum, the tail drum, and the internal drum. Thereby, even though the pressure- vibration of vibrating-combustion in rotation mode acts on the internal drum and the tail drum, those drums rotate shakingly without any restraint because the plate springs are free to deform elastically, causing the vibration to be diminished. The thermal stress is not produced because the elongation of the internal drum and the tail drum in the axial direction is not restrained completely.

Abstract: PURPOSE:To simplify a control device and improve a controlling accuracy of mixing ratio, by utilizing a third gaseous fuel to compensate for a varying index of flow rate change of first and second gaseous fuels which are supplied under a controlled flow rate or a pressure. CONSTITUTION:While a control circuit 1 controls the flow rate of LDC for a converter, a control circuit II controls the flow rate of COG for a coke oven. The controlling function of control circuit III is as follows. That is, a CO concentration detector 38 is provided at a position in a branch pipe parting from a LDG piping, the position being close to a LDG holder, where a LDG has a gretly varying calorie. The CO concentration detector 38 functions to detect the concentration of CO contained in the LDG and transmit its detection to a ratio setting device 39. The ratio setting device 39 functions to compensate for an input signal from a flow meter 32 in response to an input signal from the CO concentration detector 38, and transmit to an adder 40 a control signal regarding the flow rate of BFG furnace gas, the control signal being obtained by multiplying a compensated signal by a preset ratio and having a WI substantially equal to the LDG flow rate. On the other hand, a flow meter 41 measures merely the flow rate of COG passing through a COG piping and having a minor variation of calorie, and transmits its measurement signal to a ratio setting device 42 and a watch index control device 46. The flow rate of BFG inputted to the ratio setting device 42 is feedback controlled by a feedback signal regarding the WI value, which signal being outputted from a control circuit IV.
